This song is about ACID RAIN. Yucchh-hh! The Adirondack Mountains in upstate New York have been severely affected by this environmental problem. Emmissions from factories chemically react with water in the atmosphere, producing acid. Although the acid is weak, it concentrates (builds up) in lakes and streams. Personally I am a salt water fisher-person, but I would be very sad fishing in the lakes upstate and not catching anything.......
